Can we store a value in temp variable which can accessible?
Hi techies
I am trying to write a script which can give me a ATP of a job,
My idea is :
store a value in a temp variable, next script read the variable in next call of it and give me the diff of values which is ATP, as script is running every hours.

Can we do this in Shell Script.
If someone have better idea, please let me know

"Yes w... you can!". No clue what a ATP is, but what have you tried so far?
If the script ends it's lifecycle, variables will be lost. Maybe write it to a temp file.
If it is a permanent running script like a daemon, you can use a variable of course.

Hi
right now, I am storing the values in a temp file and whenever the script run again , it read this file and compare the values from the first one and give me the difference of values.
I wanted to remove this temp file with temp variable. Is it possible ?

my script
Code:
vbefore=`cat temp` ## Can we replace this temp file
vafter=`db2 "select count(*) from tablename" | grep [0-9]`

diff=`expr $vafter - $vbefore
